Hair care compositions with selected amino acids and selected complexes of acidic protein hydrolysates and basic fatty acid amidoamines

ABSTRACT

Hair treatment agents include selected amino acids and selected complexes of acidic protein hydrolysates and basic fatty acid amidoamines.

FIELD OF THE INVENTION

The present invention generally relates to hair treatment agents that include selected amino acids and selected complexes of acidic protein hydrolysates and basic fatty acid amidoamines.

BACKGROUND OF THE INVENTION

There is a requirement to bring about further improvement in hair care products and to provide them with further advantageous properties. In particular, there is a need to provide a conditioning complex which can ideally also be used in conjunction with oxidizing agents and surfactant agents.

Environmental influences and oxidative hair treatments often lead to impaired combability of both dry and wet hair. Furthermore, gloss and moisture balance are deleteriously affected by the attacked external structure of the keratinic fibers. A further consequence of repeated treatment of keratinic fibers with surfactant and/or oxidative agents is for severe greasiness to return to the keratinic fibers and for there to be a strong tendency towards increased dandruff formation.

It is therefore desirable to reduce the side-effects of environmental influences and of oxidative and surfactant hair treatments preferably not only as early as during the oxidative or surfactant hair treatment but also after the oxidative or surfactant hair treatment without impairing the effectiveness of the oxidative or surfactant cosmetic preparation, in particular with regard to color intensity, color fastness, lightening performance or permanent-wave action, and of preventing the keratinic fibers from becoming greasy again and increased dandruff formation. It is further desirable, in the form of a 2-in-1 product, to combine in one application step the oxidative treatment of keratin-containing fibers, in particular human hair, with the application of effective fiber protection from environmental influences, for example UV protection.

Furthermore, other desirable features and characteristics of the present invention will become apparent from the subsequent detailed description of the invention and the appended claims, taken in conjunction with the accompanying drawings and this background of the invention.

BRIEF SUMMARY OF THE INVENTION

It has now surprisingly been found that the desirable features discussed above are excellently met by a hair treatment agent that includes an active substance complex including as essential ingredients at least one selected amino acid and at least one selected complex of an acidic protein hydrolysate and a basic fatty acid amidoamine.

Hair treatment agents that include this active substance complex impart to the hair improved softening and improved gloss, and provide improved moisture balance and protection from oxidative damage. Such hair treatment agents also prevent the keratinic fibers from becoming greasy again, improve the washing resistance of dyed keratinic fibers, in particular human hair, and delay in the formation of dandruff.

A cosmetic composition according to the invention includes in a suitable cosmetic carrier, in each case relative to the total weight of the composition, at least one amino acid in a total quantity of 0.01 to 10.0 wt. %, and at least one selected complex of an acidic protein hydrolysate and a basic fatty acid amidoamine in a total quantity of 0.01 to 10.0 wt. %.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description of the invention is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description of the invention.

The present invention accordingly firstly provides a hair treatment agent including in a suitable cosmetic carrier, in each case relative to the total composition of the agent

-   a) at least one selected amino acid in a total quantity of 0.01 to     10.0 wt. %, -   b) at least one selected complex of an acidic protein hydrolysate     and a basic fatty acid amidoamine in a total quantity of 0.01 to     10.0 wt. %.

Using this combination results in surprisingly good properties of the treated hair, in particular in improved combability, improved gloss and improved elasticity and in distinctly increased washing resistance of dyed hair, and in extended durability simultaneously combined with better shaping performance in waving processes such as wet set and permanent wave.

Hair treatment agents for the purposes of the present invention are for example shampoos, hair conditioners, conditioning shampoos, hair conditioners, hair masks, hair packs, hair tonics, hair coloring shampoos or combinations thereof. In particular, hair treatment agents according to the invention are taken to be hair conditioning compositions such as hair conditioners, hair masks, hair packs, hair oils and lotions both as leave-on products, i.e. products which remain on the hair until the next hair wash, and as rinse-off products, i.e. products to be rinsed out again a few seconds to a few hours after application.

Combability is taken according to the invention to mean both combability of the wet fibers and combability of the dry fibers.

Handle is defined as the tactile properties of a fiber assembly, wherein a person skilled in the art feels and carries out a sensory evaluation of the body and silkiness of the assembly.

Shaping is taken to mean the ability to impart a change in shape to an assembly of previously treated keratin-containing fibers, in particular human hair. In relation to hair cosmetics, it is also known as stylability.

Restructuring for the purposes of the invention is understood to mean reducing the damage to keratinic fibers arising as a result of the widest possible range of influences. A significant role is played here, for example, by the restoration of natural strength. Restructured fibers are distinguished by improved gloss, by improved handle and by easier combability. In addition, they display optimized strength and elasticity. Successful restructuring may furthermore be detected physically as an increase in melting point in comparison with the damaged fiber. The higher the melting point of the hair, the stronger the structure of the fibers.

Washing fastness for the purposes of the invention is taken mean retention of the original coloring with regard to shade and/or intensity when the keratinic fibers are exposed repeatedly to the influence of aqueous agents, in particular surfactant-containing agents such as shampoos.

The compositions according to the invention including the active substance complex according to the invention are furthermore distinguished by a distinctly improved state of the keratinic fibers with regard to the moisture balance of the keratinic fibers. The active substance complex according to the invention furthermore results in clear protection of the keratinic fibers from the effects of heat, for example when blow-drying keratinic fibers. Protecting the surface of keratinic fibers from the effect of heat is in particular of great significance when using hair straighteners or hairdryers. Finally, it has surprisingly been found that the compositions according to the invention result in distinctly delayed resoiling of the keratinic fibers.

An aqueous cosmetic carrier includes at least 50 wt. % water.

For the purposes of the present invention, aqueous-alcoholic cosmetic carriers should be taken to be aqueous solutions including 3 to 70 wt. % of a C₁-C₆ alcohol, in particular methanol, ethanol or propanol, isopropanol, butanol, isobutanol, tert.-butanol, n-pentanol, iso-pentanols, n-hexanol, iso-hexanols, glycol, glycerol, 1,2-pentanediol, 1,5-pentanediol, 1,2-hexanediol or 1,6-hexanediol. The agents according to the invention may additionally include further organic solvents, such as for example methoxybutanol, benzyl alcohol, ethyl diglycol or 1,2-propylene glycol. Any water-soluble organic solvents are here preferred. Water is more preferred.

The first ingredient a) according to the invention is an amino acid. In the present application, the term amino acid is also taken to mean a structure which includes only one permanently cationic group per molecule, such as for example choline. This term is furthermore also taken to mean substances such as carnitine or taurine, since, like amino acids, they occur naturally in biological systems and in many cases behave like amino acids.

Amino acids according to the invention are selected from alanine, arginine, asparagine, aspartic acid, cysteine, cystine, glutamic acid, glutamine, glycine, histidine, hydroxylysine, hydroxyproline, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, thyroxine, tryptophan, tyrosine, valine, betaine, ornithine, 1,1-dimethylproline, hercynine (Nα,Nα,Nα-trimethyl-L-histidine betaine), ergothioneine (thioneine, 2-mercapto-Nα,Nα,Nα-trimethyl-L-histidine betaine), carnitine, taurine and choline and mixtures thereof.

If mixtures of at least two amino acids are used, the same quantities as stated above apply. In the case of mixtures, the individual amino acids are used in a ratio of 5:1 to 1:5. The ratio is relative to the weight ratio of the amino acids. If a mixture of three amino acids is used, said amino acids are in each case used in identical proportions by weight.

The second mandatory component of the active substance complex is an ionic complex consisting of an acidic protein hydrolysate and a basic fatty acid amidoamine. In the present invention, an acidic protein hydrolysate is preferably taken to mean a plant protein hydrolysate. The protein hydrolysate moiety may, of course, also originate from any desired protein source. Plant protein hydrolysates such as soy, almond, pea, moringa, potato and wheat protein hydrolysates are preferred. Collagen hydrolysates from fish or seaweed and protein hydrolysates from mussels or pearl hydrolysates are likewise included according to the invention. It is, however, essential for the present invention for the proportion of acidic amino acids in the hydrolysate to amount to at least 10 wt. %, preferably 20 wt. %, more preferably 30 wt. % and highly preferably 40 wt. %. Protein hydrolysates which meet this condition form the ionic complexes according to the invention of an acidic protein hydrolysate and a basic fatty acid amidoamine of the present invention. Protein hydrolysates based on elastin, collagen, keratin, silk and milk protein are also possible, although not preferred, according to the invention.

Possible fatty acid amidoamines are any fatty acid amidoamine with a chain length of 8 to 40 carbon atoms in the chain.

Since the acidic protein hydrolysates according to the invention may comprise a plurality of acidic groups, a plurality of the fatty acid amidoamine structures represented above are accordingly also ionically attached to the acidic groups.

The carboxy-terminal end of the acidic protein hydrolysates forms an ionic complex with the cationic or cationizable C₈ to C₄₀ fatty acid amidoamine. Examples of such compounds under the INCI name Cetearamidoethyl Diethonium Hydrolyzed Protein based on wheat or rice are commercially obtainable under the names Vegetamid® 18MEA R (Cetearamidoethyl Diethonium Hydrolyzed Rice) or Vegetamid® 18MEA G (Cetearamidoethyl Diethonium Hydrolyzed Wheat) from Seiwa Kasei.
